@squirrel Interesting. You probably strain the solid bits of the corn out before adding the milk and sugar. At least based on my experience making horchata (basically rice juice with milk and cinnamon).
@brassmerino oh, actually i don't know? there's recipes for it online but I've always bought mine, it's probably just corn, maybe a bit of milk and sugar? all in a blender
